Default OEM radio repair and mods

Hello all. I have a 100% original '91 LS that I'm trying to keep as stock as possible. I happen to be incredibly OCD about all my lights working in any car I own as well. I undertook replacing he climate control bulbs, but I feel I may have a few out in my radio. See pic below. I found a website online, I believe it's factory radio service? They seem to be the only vendor that still works with the older radios, wondering if there are any other options or if they have the market cornered on this. I want to add the auxiliary input in the front panel of the stereo so that it looks stock, as most all my music is on my iPod anyways; if anybody has any other links or suggestions for a vendor to replace lighting (if needed), and also add the auxiliary input, I would greatly appreciate it. Thank you.

Climate control bulbs done. Hazard light done. Am I missing some on the radio?

I used factory radio service to add an aux input and bluetooth receiver to my stock radio. It's really just a guy, not a large company, but the guy does excellent work at reasonable prices.

Here's a link to the thread about Factory Radio Service installing an aux-in on the back of the Nakamichi head unit of the 2000 LS400 that I sold in 2014: https://www.clublexus.com/forums/ls-...000-ls400.html

He also replaced the display's backlight bulbs.

Wonderful service and great prices - don't bother looking for somebody else to do it for you.

Default 1995 - 2000 ls400 pioneer radio and anplifier schematics

Anyone have Pioneer (non-Nakamachi) circuit board schematics and, or, parts diagrams for radio, CD player and amplifier to share??
Interested in 1990-1994,,and 1995 - 2000 LS400.

In exchange I will sift through board level discrete components to determine if any contemporary upgrades...there are probably premium grade audio capacitors and, or, more efficient devices in other areas..

Anyone upgraded or replaced capacitors in speaker crossover circuits?

Anyone undertaken these tasks?(besides LCD, and incandesent bulb replacement with LEDs)

I would like the same as well as Nakamichi info. How come its so difficult to find info on the electronic components? Does the TIS site have that info?
